Parker 169PTCNS-8-4 90 Male Elbow 1/2 in Od 1/4 in Nptf Brass

Product Description

The PARKER 169PTCNS-8-4 is a push-to-connect rigid 90-degree male elbow tube fitting designed for use in air brake and pneumatic plumbing systems. Constructed from brass, it connects a 1/2-inch OD tube to a 1/4-inch NPTF male thread using a tool-free push-to-connect tube port on each end. The fitting carries a maximum working pressure rating of 250 psi and is rated for temperatures from -40 degrees F to 200 degrees F. The nitrile O-ring sealing element ensures a reliable, leak-resistant connection under continuous vibration and pressure cycling typical of heavy-duty brake line service. Licensed technicians and fleet mechanics working on DOT-regulated air brake systems will find this fitting meets applicable federal and SAE standards.

This fitting is classified as a DOT air brake fitting, conforming to D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844. It is suited for use in commercial vehicle air brake lines, pneumatic control circuits, and related tube routing applications where a 90-degree change of direction is required between a 1/2-inch OD tube and a 1/4-inch male NPTF port. The rigid elbow orientation keeps the tube path fixed and reduces strain on adjacent fittings in confined plumbing runs.

Key Features

• Push-to-connect tube ports accept 1/2-inch OD tubing without tools for fast assembly
• Rigid 90-degree elbow geometry directs tube runs cleanly in tight or structured plumbing layouts
• Brass construction provides corrosion resistance and durability in brake line environments
• Nitrile O-ring sealing material maintains a leak-free seal across the full operating temperature range
• Rated to 250 psi maximum working pressure
• Meets D.O.T. FMVSS571.106, SAE J2494, SAE J2494-3, and SAE J844 standards for air brake service

Compatibility

Designed for DOT air brake plumbing systems using 1/2-inch OD tubing with 1/4-inch NPTF male threaded ports, conforming to SAE J844 and SAE J2494 air brake tube and fitting standards.

Installation Notes

Installation should be performed by a qualified technician familiar with DOT air brake system regulations and applicable SAE standards. Depressurize and drain the air system completely before removing or installing any brake line fitting. Inspect the tube end for squareness and burrs before inserting into the push-to-connect port, and verify the tube is fully seated before returning the system to service. Thread engagement into the NPTF port should follow standard NPTF hand-tight-plus-turns practice using appropriate thread sealant compatible with air service.
